To ensure that a RACON signal is displayed on the radar, what should you do?

To ensure that a RACON signal is displayed on the radar, it is important to consider how radar systems interact with various signals and interference. A RACON, which is a radar beacon used for navigation, sends back a distinctive signal that can be displayed on the radar screen. For the radar to effectively detect and display this signal, minimizing interference is crucial.

Turning off the interference controls means that the radar system will not filter out unwanted signals that could potentially mask or hide the RACON's response. This setting allows the radar to receive all available signals, making it possible to detect the RACON's unique return signal without it being suppressed or ignored by the interference mitigation features.

While other options may seem plausible, they do not directly facilitate the detection of the RACON signal. Increasing the brilliance of the PPI scope or adjusting the radar signal output could improve visibility or range in general, but they won't specifically enhance the radar's ability to detect a RACON signal if interference remains an issue. Likewise, using the maximum available range setting won't guarantee that the RACON signals are picked up effectively, particularly if filtering measures are still in place that could obstruct the detection of specific beacon signals.
